Behavioral Risk Factor Surveillance System (BRFSS)

The Behavioral Risk Factor Surveillance System (BRFSS) is a state-based health survey that annually collects information on health conditions, behaviors, preventive practices, and access to health care. BRFSS data are used to identify emerging health problems, establish health objectives and track their progress, and develop and evaluate public health policies and programs to address identified problems.

Note: In 2011, data from interviews with adult cell phone-only users were added to data from landline interviews. Additionally, the Centers for Disease Control and Prevention began weighting BRFSS data using a new methodology that is explained in the fact sheet. Therefore, 2011, 2012 and 2013 BRFSS data should not be compared to previous year’s data.
